and here is what I have so far, lol... Obvisouly I have not got very far....It seems so simple but I just can't seem where to begin. Do I need to nest the new for loop within the other for loop? I just need a push in the right direction.

Yes, they do need to be nested within one another. Basically, on this line here:amount = principal * Math.pow( 1.0 + rate, year ); (Line 15?)
You want the rate to be varied as in your lower loop. So one loop has to be inside the other one, and instead of "rate", you'll be using the varying "intRate".

Ok, here is what I did. When I run the program, it doesn't give results of the other interest rates. So I must not be telling the program to increment the interest rate correctly. Am I leaving stuff out of my code?
